LED high bay light cooling solution
Due to the high power of LED high bay lights, heat dissipation becomes a difficulty, because heat dissipation directly determines the product life, and product life is related to the company's reputation. short-lived phenomenon.
The current LED high bay light spends a lot of money on heat dissipation, but it is still ineffective, and it is bulky, heavy and ugly. If part of the heat can be transferred to the lampshade, it will not only reduce the cost and weight, but also improve the heat dissipation effect. .
In order to make good use of the lampshade to dissipate heat, the problem of the link from the LED chip to the lampshade must be solved, the interface for heat transfer must be less, and the thermal resistance can be minimized. Taking into account the cost advantage of COB, LED high bay light can be in the form of aluminum substrate COB, and using aluminum substrate directly as the lampshade of LED high bay light is a way with the least heat transfer interface, and using isolated power supply, safety regulations are also It is easy to pass, because even if the current breaks through the encapsulant, it is a safe current of less than 36V.
